The Old Furnace (Abraham Darby I's furnace, constructed in 1638)

Iron foundry ruins

I remember being able to walk down that tunnel! Some kind of mixing furnace
Grinder I love rusty abandoned machinery!
Abraham Darby I's 1638 furnace This furnace was were coke was first used to smelt iron
The furnace's grown The remaining brickwork is incredible
This is the secondary furnace The furnace's heart
